Biofiltration controls wastewater odour from treatment facilities, compost facilities, rendering plants, and other odour-producing operations.
Natural bark-based biofiltration media is a very effective media to help control and reduce harmful odours in the air. Bark from trees is a natural host for good bacteria to live and thrive. This develops over time to help process the airstream and odour particles that are flowing past.
Every biofilter will have a different type or variant of bacteria which is dependent on the odour type and particulates of the specific project. Bark is high in carbon, so similar to carbon-based biofilters, although bark is natural and can be more effective in the right conditions and specifications.
The different inputs that are mixed with the bark media, such as ocean shell, add trace elements to help control the pH and moisture levels in the media to aid in keeping the bacteria healthy and vibrant.
